To all whom it may concern:

Be it known that I, FRANK WV. l/Vnnn, a citizen of the United States,residing at Lynn, in the county of Essex and State of lvlassachusetts,have invented certain linprovcnients in Machines for Use in LastingBoots and Shoes, of which the following description, in connection withthe accompanying drawings, is a specification, like reference characterson the drawings indicating like parts in the several figures.

This invention relates to machines for use in the lasting of boots andshoes and particularly to machines for use in the lasting of stitch-downshoes.

As now constructed, niachinesfor use in the manufacture of stitch-downshoes are provided with a comhinedwork support and anvil block designedto support the work at such an angle to the vertically arranged last ingtool that the upper can be wiped over the last and the marginal portionof t e upper can be tucked well into the angle between the last and thesole during the lasting op erations. This block is so mounted that itsangular relationship with respect to the lasting tool can be varied byadjustment, after which the block is secured in its adjusted position.The position thus selected for the block ordinarily satisfactory forlasting operations on various kinds of shoes. However, in going aroundcertain parts of the last and particularly the heel portion, it isdesirable to set the tastenings, which pass through the lasting tool, ata greater angle than that provided by the block in its fixed position.The operative, in attempting to drive the fastenings as close aspossible into the angle of the last and sole at the heel end of theshoe, holds the shoe at a greater angle with. respect to the lastingtool or nozzle than that defined by the work supporting anvil block inconnection with said nozzle, with the result that in lasting operationsthe margin oi the sole is bent downwardly all around the heel portionthereof since it is unsupported by the block, being tipped upwardly awayfrom the block. A shoe lasted in the way described will have the heelportion of the sole dished or cupped to a variable extent depending uponthe angle at whic the shoe was held and the kind of material used forsoles. in certain grades of shoes wherein the insole is of poormaterial, and in all heelless shoes, such as childrens shoes, it isnecessary to place a piece or" leather or leatherboard in the center ofthe cuppedheel portion of the sole before applying the outersole. Thisis because the subsequent operations of laying and leveling theoutersole would otherwise fail to remove permanently the cuppedcondition oi the heelend of the completed by adding a heel, the cuppingof the heel portion of the insole during the lasting operation presentsno distortion or the heel seat which is not corrected satisfactorily bythe attachment of the heel.

It is an object of the invention to provide improved means for operatingwith the last 111g tool so that the shoe will be progressively lastedwithout any cupping oi the sole.

lt hile the conditions attendant upon the manuracture of certain gradesor types of shoes occasioned the development or the invention, it willbe understood that the invention is not thus limited in its applicationand that it comprises in one broad aspect the provision of means arranedto co operate with a lasting tool in lasting opera: tions in such awaythat the shoe will be fully and properly supported throughout thewiping and fastening inserting operations,

whatever the angle at which the 'tastenings v are driven.

In the illustrative embodiment of the invention, the means whichcooperates with the lasting tool. to eiitect lasting operations isdisclosed as comprising a freely tilt-able tahle or work supportdesigned to support the ma ginalportion of the sole during progressivelasting operations which include the driving of iastenings at variousangles along the toe, shank and heel portions ofthe solo.

Que of the di'tliculties encountered in connection witha worksupportmade freely adjustable to the various angles at which it is Idesired to drive fastenings is that of securing the proper clenching ofthe iastenings since under these conditions, the support has a distincttendency to lateral displacement away from the line of drive of thefastenings at the time the tastenings are being clenched.

' An important feature of the invention'comprises the provision of meansfor insuring the proper setting of fastenings driven at various anglesinto work supported on a freely adjustable work support.

Other features of construction reside in an organization in which thework support is vertically movable to cotiperate with a relativelystationary lasting tool and is theredriven through work on the support.

From. one viewpoint the invention resides in an improved work supportwhich is reciprocable toward and from work clamping position and isfreely movable about an aXis and provided'with a work supporting surfacehaving an. opening through which'a tool operates on the worl: upon.relative movementbetween the tool and the work support.

Other objects and features of the invention will be apparent from thefollowing detailed descriptlon and Wlll be pointed out in the claims.

on an application of William H. Borden. 1n the machine'organization, or"which a'fastening inserting mechanism forms an essential part, thenozzle 12 is constructed and arranged to operate as a lasting tool whichmaybe substantially as fully described in dated Nov. 10, 191. a novelmechanlsin herein disclosed the upper by the upper end of the post 2 2,

the Letters Patent to Prenzel No. 1,117 ,087 in lasting a shoe by the iswiped down over the sides of last progressively by the lasting tool 12as'the work is presented thereto while supported by means arranged tocoiiperate with the lasting tool in lasting operations in such a waythat the shoe will be tully and properly supported throughout the wlpingand fastening inserting operations whatever the angle at in the' whichthe iastenings are driven. illustrative embodiment of the invention, thesaid means comprises preferably a tiltable work supporting block '16pivoted at 18 upon a carrier 20 which comprises a tubular sleeve portion22 arranged to lit slidably over the upper end oi a post 2%. The carriercomprises also a base plate 26 between which and the foot plate 28 orthe post as there is positioned a spring 30 of such a tension as tomaintain the carrier in raised position against the pressure which isdeveloped ini-' tially in wipingfthe upper overthe last in the lastingoperations. In order to retain the carrier on its post and to limit themovements thereof, there isprovided a pin 32 extending from the post-2einto a slot 84 in the carrier. As shown, the tiltable member 16 ispivoted to. side pieces 36 or the carrier between said side pieces byshort pivots which extend through the said side pieces and intoandthroughthe side bars 38 of the table 16',- said side bars being f:med incidental to the .cuttingaway of the .middle portion oi the table,as shown at 40, 00 pro videfor the accommodation of a member 42 whichnormally projects into the said open ing. The member 422 is preferablycarried a convenient arrangement in providing for the attachmentot saidmember consisting in undercutting projecting portions at the upper endof the post 24 in such a way to receive the dovetailedprojection 46 onthe block and hold the same firmly in sliding engagement in thepassagewayformed by the projecting portions or flanges 44. Since thepressure on the block 42 is'always in a downward direction no otherattaching means than that provided by'the dovetailed connection de Thisconstr lCtlOlI has the i'urther advantage that the block may be readilyWithdrawn and turned end for end, thus providing a new surface when theone which has been in use becomes worn or for any reason unsuitable forfurther use. Preferably, therefore, the ends of the block have:identical construction and each coinprises, clenching suriaces and awork engaging rib 50 thefunotions oi hich will be hereinafter described.in the construction shown the post 2% with its foot plate 28 is mountedfor sliding adjustmentas indicated at 52 inFig. 1, means in the form ofabolt its 54. being provided for securing the post in adjusted positionon the work supporting post ea hereinafter described. I

- Mounted in the head is a driving shaft 62 having thereon the fast andloose clutch members 64. and 66 which are normally held inseparatcdrelation but are adapted to be placed in operative engagement bythewedge 68 connected by the rod 70 to the starting and stopping treadle72'pivoted'to the base portion of the column 74. upon a pin. or red 76.r J i Secured to the column 74 by suitable means such as the bolts78, isa bracket 8( provided with hearing portions 82 in which" is verticallymovable the work supporting post 84%. The lower portion of the worksupporting post 84- extends below the lower bearing 82 and contacts withtreadle con trolled means whereby the woi'lrsupporting post may bemanually raised. 1n the present instance this means comprises a lever 86pivoted at 88 to a lug 90 extending from the bracket 80, the rear endportion of said lever being pivotally connected at 92 to a treadle 9 1,the fulcrum or" which is preferably established on. the pin, or rod. 76.The free end portion of the lever 86 is pro-- vided with an adjustabledevice upon which the lower end of the work supporting post 84 rests. inthe present instance this device comprises an adjusting screw 96threaded into the lever 86 and provided with a hand piece 98 by whichitmay he turned to project or retract its end portion 100 to regulatethe drop of the work supporting post. When adjusted the screw 96 maybeisecured from accidental displacement by a clamping bolt 1102 passedthrough the split end of the lever 86. In the illustrated machine thepost 8 1 is provided with hearing portions which comprise lugs 10%secured to, the postabove the upper end of the bearing82 in which thepost slides said bearing 10 1 being arran 'ed to engage the .tlat' face106 of an arm 108 adjustably secured to the bracket 80 by suitable meanssuch as the bolts 110 which pass through elongated slots in the arm 108,the construction being such-that the arm 108 may be properly adjustedinto bearing relation with the lugs 104 which may ride on the flat faceof the arm as the post is raised and lowered. By this constructionrotative movement oi the work supporting post prevented and since thebearing between the lugs 10% and the arm 106 is close to thework'supporting portion of the post, spring action ot the post under thestrain of inserting fastenings into the boot or shoe is prevented. v

in the use of the construction thus far described it will be apparentthat upon depression oi the treadle 94: the work supporting post 8%which as whole may be con veniently termed the work support will beraised manually toward the fastening inserting mechanism to clamp thework against the opposed abutment which, in the illustrated stitchdownstaple lasting machine comprisesthe lasting tool 12. When the operativehas satisfied himself that the desired wiping action of the upper aboutthe last will be secured and that the'fastenings will be properly driveninto the work, the starting treadle 72 will be depressed to set thefastening inserting mechanism into opera tion. in the illustratedmachine means 18.

provided which; upon starting into operation the iastenin g insertingmechanism, will insure that the work support is fully raised and lockedin work clamping position provided that work support movement towardsuch position has been manually started or initiated. This means in theconstruction shovn comprises a wedge yieldingly actuated from the. meansfor operating the tastening inserting mechanism. Preferably the hraclret80 is provided with guideways 112 one at each side of the bracket 80 ineach of which is mounted for reciprocating move-v ment a wedge 1141;Each guideway' 112 may be formed by separated upper and lower flanges1.16 which thus provide a passage between them for a pin 118 secured toeach wedge 11a. Connectedto each pin 118 is a rocker arm 120 secured toa rock shaft 122 mountedin suitable bearings which may be convenientlyformed in the bracket 8O sufficient play or loose motion being providedbetween the pins 118 andthe connections to permit rectilinear movementof the wedge without binding of the pa ts. .llhe rock shaft122 hassecured thereto an arm 12% which; may be yieldingly connected. tosuitable meansactuated from the driving shaft 02 to impart to said arm12 i, and through it and associated elementsas described, to the wedges11 1,.the desiredmovements, aswill presentlyappcar. Secured to themaindriving shaft is a earn 126 having a cam path engagedub a pin or rollermounted on an arm 128 which is mounted for rocking movement onthemachinehead. As shown the arm 128 is mounted on the pin or stud carried bybearings 1-30 projected "from the head trance 60, the construction'beingsuch that as the driving shaft is rotated and the fastening inserting"mechanism is consequently operated, the arm. 128 will be rocked by thecam 12b. The aim 128 is yieldingly con nected to the arm 12a abovedescribed, and in the present instance such connection is made byproviding the arm 128 with lugs for the support of a pin which passesthro 'h the upper end portion of the wedge oper ting rod 132. The lowerportion of the rod passes loosely through the rocking stud mounted forrocking movement in the lie-urin carried b the arm 12% and has mountedon its end the set nuts 13%. Surrounding the rod 132' and seated atoneend I on the top of the said rocking stud and'at its other end againstthe'under side of-a collar 136 adjustablysecured to the rod 132, isaspring 138, the construction being such that as the cam 126 is rotatedby the main driving shaft 62, the rod 132 will be reciprocated to impartto the wedges 114 reciproeatmg movement in their respective guidesprovided such movement of the wedges is not eliectively obstructed.Should the wedges meet an effective obstruction sufficient to preventsuch movement the rod 132 the operative, the a'xesof the pins androllers v are slightly below vthe front edges of the will still bereciprocated but, instead of moving the arm 124 on thedownward movementof the rod, the spring 138 will yield and simply be compressed, thuspermitting the wedges to remain at rest. Projecting froin' the worksupportingpost 8 at the sides thereof in front of the'wedges 114 arepins 140 carryingrolls 14:2 for engaging the Vwedges 114 as the latterare movedforward by the automatic means described. ,lVhen the worksupport is in its lowered position, as when the treadle 94 is notdepressed by wedge inclines, and if atsuch times the starting andstopping treadle -72 be depressed to start the machineythe moving meansfor the wedges will be operated but the rollers and pins in the worksupport will prevent such movement'of the wedgesand.

r the work support will remain in lowered position. 1 Upon manuallyliftingthe work support to or toward work clamping .position, as bydepression or partial depression of the treadle 94;, then the axes ofthe pins and rollers will have been sufiiciently raised to permit thewedges to engage beneath them as the wedges are operated from the mainshaft and thus the work support will tail, the operative will presenttherlasted be lifted to; full workclamping position and locked for theinsertion of fastenings.- For more complete descript on of the automaticmechanism for operating the. work supporting post, reference should behad tothe co-pendin application of Matthias Brock, Serial 1 o. -4tl,915, filed August 11, 1915. I

In performing lasting operations with the machine which has beendescribed in dedrive the fastenings. The operative thende-' presses thetreadle 94: to cause the work to engage with the lasting tool 12 whichoperates to'wipe the upper down over the side .of the last and to tuckit into the angle between the last and the projectingmargin of the sole.During the'wiping and pressing operations which accompany the lasting ofthe upper, the carrieri20r for the tiltable tablelfi yields slightlyrelatively to the post 2% so that at the termination of the wipingoperationthe upper is firmly clamped into the angle of the last and soleand upper and sole are finally pressed against the block 42 whichcarries the'staple clenching cav-' ities. Thus, b relative movementbetween the tiltable tab e and the clenching block the latter operatesto securely set the fastening in place, thus terminating the lastingopera- I tion. As heretofore described, the block 42 is provided withaprojecting rib 50 which is constructed and arranged to engage the lowersurface of the sole only after a slight 7 relative depression of thetiltable table with its carrier so that by engagement of said rib withthe sole any lateral slipping movement of the work on the tiltable tableis prevented.-

'While the engaging rib thus described-is not an absolutely essentialfeature of the construction, 1t has distinct advantages inasmuch aswlthout such a rib the-operative must exercise considerable pressurelaterally on the work to prevent it from slipping during the fasteninginserting operation. By reason of the construction and arrangement ofthe work-support operating mechanisms the operative is -enabl'ed tostart the lasting operatlon under manual control by depression' of thetreadle 94 but such manual condriven means forlifting the'work supporttrolisquickly supplemented by the power to effect the completion of thelasting opera tion, and especially thefirm setting of the fasteningunder conditions which insure a perfect clenching of the fastening whilethe work is securely clamped in lasted position.
